SAMSON FOX, OF HARROGATE, ENGLAND.

BOGlE-TRUCK FOR RAILWAY-CARRUIAGES.

SPECIFICATION forming part of Letters Patent No. 505,159, datedSeptember 19, 1893. Application filed September 21, 1892. Serial No.446,429. (No model.) :Patented in England February 26, 1892,1To. 3,799.

To all whom it may concern.-

Be it known that I, SAMSON Fox, a subject of the Queen of Great Britainand Ireland, residing at Harrogate, in the county of York, England, haveinvented Improvements in Bogie-Trucks and Under Frames for Railway-Carriages and other Vehicles, (for which I have obtained British LettersPatent No. 3,799 of 1892,) of which the following is a speciication.

This invention has reference to constructions of bogie trucks wherebysuspension links or bolts and connections such as are usually employedin supporting the lower transverse spring beam (sometimes called a swingbar), as also in some cases the spring beam or swing bar itself, can bedispensed with; like- Wise to constructions whereby when springs actingvertically (whether they be coiled, cylindrical or of other shape) areemployed either as bearing springs or as auxiliary supporting springs,the bogie frames or vehicle under-frames can be vertically adj ustedwhen desirable for any reason, such for example as to compensate for thesettling down of the springs or wear of wheel tires or axle brasses.

In the accompanying drawings, Figures l, 2 and 3 are respectively a sideelevation, a part central transverse section, and a part plan of a bogietruck constructed according to this invention, a part of the under frameof a vehicle supported thereby, being shown in dotted lines in Figs. 1and 2. Figs. 4, 5 and 6 are similar views to Figs. 1, 2 and 3respectively, illustrating a modified construction. Figs. 7, 8 and 9 arealso similar views to Figs. 1, 2, and 3 illustrating a further modifiedconstruction. Figs. 2 and 5 are drawn to a larger scale than theremaining figures.

Referring to Figs. 1 to 3 inclusive, the bogie frame comprises stampedor pressed side plates 11 connected by transverse members 2, 2. 3 is thebolster to which the under frame 4 of the vehicle is pivoted by thecenter pin or bolt, 5. 6 6 are the bolster bearing springs, shown aslaminated elliptical metal springs, of which there are in the exampleshown, two pairs at each side of the bolster. 7 is the lower transversespring beam. This beam which can be of any suitable form and material,is arranged to be capable of easy lat- To obviate all liability of thebolster bear-4 ing springs to become displaced from between the bolster3 and spring beam 7, the strap 10 of each spring is made in one withaplate l1 that is rmly bolted to the bolster or spring beam, as the casemay be, by studs or bolts and nuts 12. Also to enable the ends of thebolster bearing springs 6 of each pair to roll 0r move relatively toeach other in a lateral direction without undue displacement, theadjacent ends of each pair of springs are connected by links 13 and pins14.

In the arrangement shown in Figs. 4, 5 and 6 the spring beam isdispensed with, the bolster bearing springs 6 being supported by a solebar carried by the bogie frame and in relation to which the lower springof each pair can angle or rock so as not to unduly impede the lateralmotion of the bolster 3, to which the upper spring of each pair isbolted. rllhis mode of mounting the springs can be carried out invarious ways. In the construction now being described, the sole bar isin the form of a dished plate l5 fixed to the side plates of the bogieframe and the top of which is formed with a recess 16 having a concavebearing surface to receive the correspondingly formed adjacent portionof the strap 10 of each of the lower adjacent bearing springs 6.

In the modified arrangement shown in Figs. 7, 8 and 9, the bolsterbearing springs 6 are in the form of coiled metal springs arranged intwo groups, one at each side of the bogie. Each group rests upon a plate16 formed with a lower convex portion 16ad carried by a correspondinglyformed portion of the sole bar 15 fixed to the bogie frame. Thesesprings are prevented from becoming displaced, by pins 17 17 whichproject into the ends of the springs and are fixed to the bolster 3 IOOand plate 16 respectively. It will thus be seen that in each arrangementthe sole bars serve to carry the bolster and bolster bearing springs,thus dispensing with the suspension links or bolts and connectionsheretofore usually employed for this purpose.

To enable bogie Atrucks or vehicle under frames to be adjustedvertically a cross head of adjustableform is arranged to bear on the topof the spring carried by each axle box and between each. cross head andthe bogie frame are interposed suitable means such as adjusting screwsfor varying in a vertical direction the position of the bogie framerelatively to the cross head. Such an arrangement is shown in sideelevation at the right hand side of Figs. l and et. 18 is across headarranged to bear upon the top ot' the coiled spring 19 the lower end ofwhich rests upon the top of the axle box 20. 2l are suspension boltspassing through cross head from which they are suspended, and throughthe lower inwardly bent lianges l*L ofthe corresponding side frame l.Each bolt is provided with a plate 22 upon which the side frame directlybears and with nuts 23. With this construction it will be seen that byadjusting the nuts on the suspension bolts, the vertical position of thebogie frame can be varied to suit requirement. In each arrangement thebolster 3 is provided at each end with a pressed metal bearing piece 24.upon which a bent metal bearing piece 25 fixed to the under frame 4slides.

What I claim is*- l. A bogie truck having side-frames and ixed supportstherein for the bolster supporting springs, a bolster free to movelongitudinally independently of the side-frames, springs connecting saidbolster and sideframes whereby longitudinal motion of the bolster isobtained, and the swinging bolster is dispensed with, substantially asdescribed.

2. A bogie truck havingside-frames, spring supports secured thereto, anupper bolster, bolster-bearing springs connecting the bolster and theside-frames, and mechanism for allowing the motion of said springs whenthe bolster moves over them longitudinally, substantially as described.

3. A bogie truck having side-frames, sole bars secured tothe inner sideof the sideframes, an upper bolster, bolsterbearing, springs connectingthe bolster and the sideframes, and mechanism for allowing the motion 0fsaid springs when the bolster moves over them longitudinally,substantially as de carried by said bogie frame and supporting saidbolster, said springs being arranged in pairs and having their adjacentends jointed together thereby allowing motion transverse of the car onlysubstantially as herein described for the purpose specified.

5. A bogie truck comprising a bogie frame, laminated metal bearingsprings carried by said frame and connected together in pairs by linksjointed to the ends of the springs, and a bolster carried by saidsprings and fixed to the upper spring of each pair substantially asherein described for the purpose specified.

6. A bogie trucky comprising a bogie frame, sole bars secured to theinner side thereof, a bolster, and laminated metal bearing springssupported by said sole bars, said springs being jointed together inpairs, fixed to said bolster and mounted to move laterally in relationto said sole bars substantially as herein described.

7. The combination with a truck frame and bearing springs therefor, ofcross heads arranged each to bear on the top of one of said springs andadjusting mechanism arranged between each of said cross heads and saidframe and supporting the latter and axle boxes bearing against saidsprings and sliding vertically only in the pedestal substantially asherein described for the purpose specified.

8. The combination with a bogie frame and bearing springs therefor, ofcross heads arranged to bear on said springs, and bolts suspended fromsaid cross heads and provided with adjusting nuts upon which said framerests and axle boxes bearing against said springs and sliding verticallyonly in the pedestal substantially as herein described for the purposespecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
